Definitions
- the invention relates to a method for erasing
- Such storage services are, for example, cloud storage providers.
- cloud storage providers it is common that a user does not know where his files were stored.
- user data is stored in a cloud storage service on servers distributed worldwide. Also it is possible that not all the data of a user is on a server but in different places
- the object of the invention is to describe a method for deleting information from a memory provided via a data network with dynamic memory location allocation. It is another object of the invention, the Use of such a method and to describe suitable devices.
- the method comprises the
- Location assignment does not tell a user where and how their files are stored. Loads the user into memory, such as a file
- Cloud storage this file is stored in any location, such as a server of the cloud storage provider.
- the user is, for example, via a
- Restore hardware storage of the server The data stored by the storage provider is copied periodically to create a backup of the data. Also on the information about the location and the
- the files for describing the remaining memory are files whose content can be determined bit by bit. These files are especially containerless files. Often files have a specific filegroup
- predetermined contents of the files are a sequence of logical ones corresponding to the particular length of the files.
- the name corresponding to the particular name has a format-specific file identifier.
- An advantage of such an embodiment is that all files be overwritten, which can be assigned to a user. This will cause any files and
- a third aspect of the invention is a
- Computer program product described comprising executable program code, wherein the program code is adapted to, when executing the computer program product by a
- a fourth aspect of the invention is a
- Data network connection to establish a connection to at least one provided over a data network memory with dynamic memory allocation and the
- Computer system is further adapted to carry out a method described above.
- FIG. 2 shows a computer system according to an embodiment.
- Figure 2 shows an arrangement with a computer system CS and a memory CL with dynamic memory location assignment.
- the computer system CS has a data network terminal DA.
- the computer system CS can establish a connection to a network via the data network connection DA.
- the memory CL is as well as the computer system CS to the network
- the computer system CS is in this case, for example, a home PC, a server of a company, a mobile phone or a so-called tablet PC. Basically, as a computer system CS any system can be viewed, which has data on a
- Memory CL is a cloud memory in the exemplary embodiment.
- the provider of the memory CL provides the user of the
- Computer system CS a certain amount of space for
- Computer system CS usually displayed via a user interface. However, this user interface only shows the user the amount of memory available to them. It does not show where this memory is. An allocation of the available memory to a real memory at a specific location takes place only on the part of the memory provider. For example, if a user saves two files to him
- Memory is allocated and the available memory is reduced according to the size of the files
- Memory is usually much larger than the memory available to a single user.
- the storage provider On the user interface of the user of the computer system CS is now made by the storage provider, a link or a link, or a reference to the actual data of the user.
- the user of the computer system CS On the user interface of the user of the computer system CS is now made by the storage provider, a link or a link, or a reference to the actual data of the user.
- Computersystems CS at any time retrieve its data. However, the user is not presented with the actual physical locations of the files. If the user now deletes the files from the user interface, he simply deletes the links that are displayed on the user interface
- step 1 the size and name of files stored in the memory CL are determined. For this purpose uses Computer system CS the data network connection that exists over the data network connection DA. Determining the size of the stored files becomes the occupied one
- File extensions or identifiers which are given when a file is saved. This includes, for example
- step 2 files are created that have a
- the files are in
- Cloud storage takes place, but that actually takes place at the physical storage location overwriting.
- step 4 only the file size provides an indication of the original stored data.
- step 4 a file or several files are created in step 4, which are stored in the
- Embodiment as well as the created files with logical ones (OxFF) is described.
- This file is just large enough to fill all of the remaining memory available to the user of the CS computer system.
- step 4 may be performed prior to step 3. After performing both steps 3 and 4, the whole is available to the user
- Step 5 now waits until the
- Storage provider of the cloud storage makes a backup copy of the data.
- the backup copy is also overwritten with logical ones and there is no longer any information that is due to the original data of the user of the computer system CS.
- Such a method may be executed by a software on the computer system CS, which is a
